That's not specific for Erlang. You need someone familiar with
generic Unix/Linux system-level stuff and the configuration of your
server to help you. Google "ldd LD_LIBRARY_PATH".
Off-hand it appears openssl was installed in a non-standard location.
Don't do that unless you use LD_LIBRARY_PATH (or static linking, but
that's frowned upon). On any reasonably modern Linux distribution you
should just use its default openssl (+ development libraries, they are
usually separate and many forget to install them).
